...RED FLAG WARNING IN EFFECT FROM 1 PM TO 9 PM PDT TUESDAY...

.DISCUSSION...Hot and dry weather continues this evening, with
above normal temperatures through Thursday. Low pressure offshore
from central California will move northeast into northern
California on Tuesday with a surge of moisture aloft into the
area. This will result in isolated to scattered coverage of
thunderstorms Tuesday afternoon through Tuesday evening. With the
trough north of the site on Wednesday, drier air and weak ridging
at the upper levels is expected to produce only cumulus buildups
late in the day. The approach of another trough will bring another
slight chance to chance of late day thunderstorms on Thursday.
